Clutch stuck to floor

Dual wheels

09 Audi A4 clutch after sticking to the ground, thinking it may be the clutch master cylinder? Anyone know if this is inside or outside the gearbox in this model?

Master cylinder is generally attached to the pedal, slave cylinder is on or in the bell housing.

I'm not trying to be funny or smart, but get down on your knees and using a light , press the pedal with your hand, and see if it's catching on something in it's travel. See if you can physically pull it back to its normal position. If it won't come back, then the problem is within the master cylinder itself, and it will have to be taken off, and stripped down to see whats wrong. It may need to be replaced, but you wont know that until its stripped down. It should not prove to be the most expensive job in the world. Good Luck with it.

Yea I did that and the clutch isn’t catching on anything I can lift it back up with my hand but there is no pressure holding it so when I press on it it goes back down to the floor

Is the master cylinder full of fluid? Have a look underneat the car and see if you can see any fluid leaking. Most likely its leaking from the clutch slave cylinder. No fluid equals no resistance to the pedal when its depressed.

Yea it seems to have emptied out of it

Ok,you should be able to see exactly where its leaking,,,as I said, it's most the slave cylinder which operates the clutch. As far as I know, the slave cylinder on the A4 is external, which will make it easier to fix.But from here onwards, you will need professional help, get a mechanic to have a look at it for you.

Any smell of burning oil when driving? Just having the wifes Ford fixed, slight smell of burning for ages which was oil from the slave cylinder dripping on the clutch plate and burning off so no sign of oil under the car. That car has an internal slave cylinder so needs splitting to get at the slave cylinder and of course needs a new clutch. If you are lucky your slave cylinder is outside the bell housing.

Looks like you are right
No smell of burning but it looks like the Slave, I’ll bring it to a mechanic, any idea of what it will cost?
Thanks all for the help

All depends on where the slave is located...on the outside of the bell housing, its accessible and there fore easier to work on, means less time / labour, plus the fluid tends to go on the ground, and not into the bellhousing / clutch assembly.
On the other hand, if its inside the bell housing, then the transmission / bellhousing has to be split from the engine, so more work=more time=higher cost. One drawback of the internal slave cylinder is that when they leak, the fluid can get onto the clutch assembly and damage the disc which means replacing it. Plus its normal practice to replace the pressure plate and thrust release bearing when replacing the clutch disc. Hopefully, yours is outside the bellhousing.

It’s inside the bell housing on this model. And the ain’t a nice job to do. We do afew audis and the last one I did was a pig plenty to go wrong. Shafts need to be removed from the gear box so then seals will need to be changed. Unfortunately my advice would be to change the clutch as in the three piece clutch kit. What mileage is on it. If it’s high I would imagine might also need a flywheel. It’s gona be a expensive day at the office and I don’t mean that in a smart way. But if u need a flywheel aswell it’s not going to be nice.
But just so your aware as I said it is quite a expensive job so no mechanic will just change the slave cylinder it will have to get the full kit.
If ya need any more advice il be happy to help u out

Ahh the crap happens again when inside the bell housing.

Fill the reservoir with fluid an press the clutch a few times to pump it through. If the master is leaking you'll probably find evidence around the pedals.
Is there a separate brake and clutch reservoir on your car?

Agreed, no point in doing all that much ripping, and not replacing everything. At least that way, when its done, you can forget about it. I've never really understood why they shifted the slave cylinder from outside the bell housing to inside it. I presume that there was some advantage in it, but for who? or what? Automatic assembly? Right pain in the ass though.

I was charged 950 incl vat parts and labour for clutch and flywheel on mine a few years back .

They possibly make it cheaper combining slave cylinder and release bearing into 1 unit and would be lighter in weight.

Yes I would imagine this would be in and around a rough idea on price all depending on which the car needs

When they first introduced dual mass flywheel's a few years ago, they were seriously expensive, but I'd say ( guessing here now) that the prices would have dropped a bit by now, especially if using non genuine parts. Only one way to find out for sure though, ask around and see if you can get a few quotes. Good Luck, and let us know how it goes for you.

Yes they have dropped quite abit but it’s defo gona be the guts of 600 euro on parts alone. Then when the gearbox comes out I’m fairly sure there’s gona be a oil leak coming out of the crank seal. There are a number of other issues that will need attention. So I still stand by the op is going to be looking in and around 1000.
My advice would be get one of the mechanics to do it as a nixer on the side. You might get abit if better value

I drove a car one time with slave cylinder gone so no clutch from kilkenny city to waterford city down the back roads, could change gear with some precision and timing but burned out starter motor in waterford city

You could have pissed into the reservoir to get you a bit further.

Although it sounds a bit unorthodox, its soundly based on the scientific principles of air being compressible , while liquids are not, it would work, and get you home,,, Although whoever has to work on it afterwards, might not appreciate it so much...:):):)

I'm travelling back a bit in the past, but I remember driving vehicles which did not have a full synchronized gearbox,,1st and reverse were Ok, because the car / truck were normally stopped, but all other gears were "crashed". With practice People got very good at timing the gear changes, they would shift from say 2nd to neutral, press the lever against 3rd and at exactly the right moment push it into gear. This involved listening to the engine revs, the speed of the car,and developing a sense of the right time to move the gear lever., engaging it without metal to metal screeching. Kamaz truck drivers were past masters at this. I often marveled at the sight of a MAZ truck, loaded to the makers name ( and beyond ) travelling uphill and listening to the gear changes, which were generally faultless. No mean feat in that particular truck..:)

I remember a story during the war was told a vehicle fleeing from the advancing troops had a mishap when it ran out brake fluid in the desert and all brake fluid used up and no clutch pedal,all standing around scratching their heads of what to do when flash Harry took it out :eek::eek:and pissed into the reservoir and been a fluid they managed to escape:D:D

Is it definitely inside the bell housing?

Bmw123 says that he has done several in the Garage where he works ,and that they're inside the housing, so I'd go with that. I've replaced clutch's and flywheels,just not in the same car as yours, so I know what is involved.

The Continental Op

Easiest way to check if its inside or out is to check online for a clutch kit and see whats in it. I randomly checked some A4 kits online and the ones I saw were all inside and part of the release bearing. Prices weren't too bad even with the flywheel as low as £150 including postage from the UK but of course thats probably no good atm as it wouldn't arrive for ages.

I'd just be a bit wary of the quality of what I'd be buying, a DM flywheel @150 is very good value, but as long as its from a recognised brand, should be OK. As for buying anything from the UK at this point in time, personally I'd be waiting until they make up their minds on Brexit. With to normal delivery's falling behind due to Christmas, there's a good chance that it will not be delivered before Brexit kicks in. And at the moment, thats unknown territory. Shop at home or in the EU, I find Germany pretty good.

In the master cylinder?? :rolleyes: Ah, no, drink one or two litres, let the pressure build up, then take carefull aim and let 'er rip !!! ;);)
